    CS1 student grade prediction: unconscious optimism vs insecurity?
    2020-07 - Sobral, Sónia Rolland
    The difficulties of many students in introductory programming courses and the consequent failure and drop out make it necessary to look for motivation strategies for them to be successful. One of the strategies that is touted in the literature is self-assessment to compromise and motivate students. As we had doubts about the possibility of this strategy, we did an experiment and asked the students to predict the grades of the two tests and the two projects during a semester. Even knowing the correction grid and exercises that involve programming languages, which shows the result to the programmer, we found that the students' forecasts were not very accurate. In the first test we found that the worst students said they were going to get reasonable grades and much better than reality, while the best students thought they had worse grades than they actually had. The other moments of evaluation did not have as severe results, but forecasts continued to be inaccurate. We did tests by gender, by age, for being a freshman or not, for having taken a computer course in high school and for previous knowledge of programming languages: none of these variables proved to be as significant as the students' grades and their corresponding insecurity-fear or optimism-unconscious.

    CS1 and CS2 curriculum recommendations: learning from the past to try not to rediscover the wheel again
    2020 - Sobral, Sónia Rolland
    Initial programming curricular units are of great importance to computer courses. There has been very important work with curriculum recommendations, notably those from Association for Computing Machinery (ACM) and later ACM in conjunction with the Institute of Electrical and Electronics Engineers (IEEE): so far almost twenty curriculum recommendations have been published. Computing is a constantly evolving area, as is society and the way new generations learn. Why are so many recommendations needed? And what are the developments in these recommendations? This article lists initial course units that are suggested or used as examples in each of the curriculum recommendation reports, both initial and generic, and those that address a specific area, namely Computer Engineering (CE), Computer Science (CS), Information Systems (IS), Information Technology (IT), and Software Engineering (SE). This study is of great importance for those who have the responsibility to design and redesign curricula as it points out a number of different paths, namely in relation to the already mentioned distinction by areas but also the distinction that is made by university size, previous knowledge of the students, and also duration of studies, among other variables. Knowing history makes it possible to understand the present and even make better choices for the future.

    Bloom's Taxonomy to improve teaching-learning in introduction to programming
    2020 - Sobral, Sónia Rolland
    Students in computer science courses entering higher education begin with computer thinking and programming languages in a curricular unit (CU) that can be referred to in various ways, like CS1 or programming fundamentals. This CU is very important for the academic and professional path of those students. Teachers and those responsible for those courses must carefully define the learning objectives, the learning strategies and the assessment of this teaching-learning. Bloom's taxonomy, in its different variations, is a powerful tool that helps in these tasks and that gives clear indications on the language that is to be used - which is useful for perceiving both the level of colleagues and the level of accreditations and assessments of courses. This article provides a detailed description of Bloom's taxonomy and its changes over the years. Studies carried out in the context of teaching fundamentals of programming and using Bloom's taxonomy are listed and analyzed. In the end, the conclusions and the definition of future works are made.

    Is pair programing in Higher Education a good strategy?
    2020 - Sobral, Sónia Rolland
    Pair programming is by definition two-person programming on the same computer. The technique has been used in many higher education institutions and has been reported in some scientific articles, usually for introductory to programming courses. The aim of this article is to make a situation report analyzing the scientific production on pair programming for curricular units of introduction to programming in higher education, measuring the advantages and disadvantages of the strategy. The sample was composed by 153 articles indexed in Elsevier’s Scopus. The results obtained by bibliometric analysis showed the publication rates, authors, in which journals they are published, which are the organizations and countries that publish the most, which are the most cited articles and what their purpose. The benefits reported are generally better code, improved programming and group skills, advantages for women and reducing the work of instructors. The problems are group compatibility: there are studies that randomly distribute pairs, while other use personality tests or knowledge self-assessment.

    Flipped classrooms for introductory computer programming courses
    2020 - Sobral, Sónia Rolland
    Teaching and learning how to program are not easy tasks. Disapproval and dropout rates are a concern for everyone concerned with the topic. Therefore, it is necessary to look for strategies that improve the motivation of students who start a programming course, also improving success rates and decreasing dropout rates. The inverted class model, or flipped classroom, has been used in several experiments, showing very good results. The objectives of this teaching-learning technique is to change the traditional order: students have contact with new subjects before the classroom, using videos, texts or other material, as well as small online tests to check their knowledge. In this way, the face-to-face classes are reserved for discussion, doubts and application of previously acquired knowledge. The purpose of this paper is to analyse the scientific production on Flipped classrooms in introductory programming courses indexed in Elsevier’s Scopus. The sample is composed by 45 articles in total. The results obtained by bibliometric analysis showed when and where those documents are published, who the authors are and what the focus of said articles is. We also analysed the most cited documents. We made a summary of the articles, namely in what refers to the sample size of the experiences, which programming language is used, in which universities the articles are made, which technology is used, as well as which methods are used in order to create inverted classes and which are the objectives and results of these experiences reported on the articles.. We managed to get a global view of the theme, getting a strong analysis for those who want to use flipped classrooms for teaching programming.
